THEODORE RAUSGHENBAGH, OF EVANSVILLE, INDIANA.

MACHINE FOR FORMING AND FINISHING CONCRETE AND CEMENT CURIBS AND GU'ITERS.

Specification of Letters Patent.

Patented Feb. 27, 1912.

Application filed March 14, 1910. Serial No. 549,137.

To all whom it may concern:

Be it known that I, THEODORE RAUSCHEN- BAOH, a citizen of the United States, residing at Evansville, county of Vanderburg, and State of Indiana, have invented certain new and useful Improvements in Machines for Forming and FinishingConcrete and Cement Curbs and Gutters, of which the following is a specification.

My invention relates to machines for forming and finishing concrete and cement curbs and gutters.

The present invention has for its ob ect the provisions of a simple, strong, durable and inexpensive machine of novel construction, for forming and finishing concrete and cement combined curbs and gutters and seeks to provide a machine of the character set forth which will be adapted to distribute the finishing mortar or the like onto the previously formed combined curb and gutter, to smooth the said finishing mortar on the curb and gutter and to remove any irregularities thereon and which will insure accuracy of operation, evenness of distribution of the finishing mortar and enable the operator to rapidly and easily smooth off and.

finish the combined curb and gutter whether the latter be straight or curved.

The invention is carried out by the provision of certain improved features and novel combinations and constructions as will more fully appear hereinafter.

In the accompanying drawings: Figure 1 is a side elevation taken in the direction of the arrow of Fig. 4; Fig. 2, a bottom view; Fig. 3, a side elevation looking opposite to that of Fig. 1; and Fig. 4, a vertical section on the line 44 of Fig. l.

As shown by dotted lines in Figs. 1 and 3, and in full lines in Fig. 4, 1 and 2 designate the inner and outer boards commonly used for the formation of a combined curb and gutter to be made of concrete or cement.

One feature of my invention consists in the provision of a track or rail 3 surmounting either or both of the boards 1 and 2, thus insuring accuracy of operation of the machine.

The machine frame consists of side plates 4 and 5 connected by braces 6. Journaled in removable brackets 7 connected to the plate 4 by any suitable fastening and also journaled in openings 8 in the plate 4 are sheaves 9 which are adapted to fit and travel on the track 3. These sheaves are preferably disposed toward the ends of the plate 4, two being used, but when the machine is to be used on a rounded corner of curbing and gutter, the brackets 7 are removed and one of them is secured to the central part of the plate 4, holes 10 being provided for that purpose, while another hole 11 is provided to receive the axleaof the sheave. The plate 5 is provided with a bracket 12 in which and in said plate is journaled a wheel 13. It will be understood that the wheel 13 may be grooved and a trackemployed on the side board 2, if desired.

Rising from and secured to the plates 4 and 5 is a tapering hopper 14 whose delivery mouth is seen at 15 in Fig. 2, through which the finishing mortar or the like gravitates onto the curb which is to be smoothed and finished. Depending from the plates 4 and 5 and suitably secured thereto are the edging or beveling plates 16 and 17 which smooth off the inner and outer edges of the combined curb and gutter, the plate 16 demarking or defining the joint of the curb with the sidewalk.

Secured to and extending from one to the other of the plates 16 and 17 are the smoothers and finishers 18 and 19 which are duplicates and are disposed parallel to each other, said smoothers or finishers being in outline the same shape as the combined curb and gutter, and they are rounded at their edges 20 and also rounded at their bends 21 so that the curb or gutter will not be torn or damaged but, on the other hand, there will be a gradual smoothing and applying pressure exerted thereon and the finishing mortar or the like will be easily and regularly applied at all points.

When the machine is traveling along the board 2 and track 3, the lower faces of the smoothers and finishers are separated a suitable distance from the face of the curb and gutter, which has been previously formed, to permit the free passage of the layer of finishing mortar which is to be applied to the curb and gutter.

When the machine is in operation, the hopper 14 is filled with the finishing mortar, cement, or the like, which, as the machine is drawn along, gravitates through the mouth 15 and is applied to the curb and gutter and the whole smoothed off.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a machine for smoothing and finishing curbs and gutters, the combination with a movable hopper having a discharge mouth, of a pair of twin smoothers and finishers having relatively broad, flat bottoms and corresponding in shape to the outline of the curb and gutter and disposed below the hopper on opposite sides of and adjacent to the delivery mouth thereof and movable with said hopper and supporting means for said machine adapted to maintain the bottom of the smoother or finisher above a previously formed curb and gutter.

2. In a machine for smoothing and finishing curbs and gutters, the combination with a movable hopper having a discharge mouth, of a smoother and finisher having a relatively broad, flat bottom corresponding to the outline of the curb and gutter and disposed below the hopper at one side of and adjacent to the delivery mouth thereof and attached to said hopper, supporting rollers located on opposite sides of the machine adapted to travel on opposite sides of the previously formed curb and gutter and to maintain the bottom of the smoother or finisher above a previously formed curb or gutter, and depending plates carried by oppo-- site sides of the machine which extend down below the rollers aforesaid and are adapted to smooth or finish the inner and outer faces of the curb and gutter.

3. In a machine for smoothing and finishing curbs and gutters, the combination with a movable hopper having a discharge mouth, of a pair of twin smoothers and finishers having relatively broad, fiat bottoms, corresponding in shape to the outline of the curb and gutter and disposed below the hopper on opposite sides of and adjacent to the-delivery mouth thereof and attached to said hopper, supporting rollers on opposite sides of the machine adapted to travel on opposite sides of the previously formed curb and gutter and to support the finishers above a previously formed curb or gutter,'and depending plates carried by opposite sides of the machine which extend down below the said rollers and are of a length as great as the space occupied by the smoothers and finishers.

4. In a machine for smoothing and finishing curbs and gutters, the combination with a frame, of one or more grooved traction wheels carried by said frame and adapted to travel on a track or other device on one of the curb and gutter boards, a traction wheel carried by the frame and adapted to travel on the other of said boards, a hopper carried by the frame which is adapted to deliver the material onto the curb and gutter, and a smoothing and finishing device corresponding to the outline of a curb and gutter and carried by the frame which has a relatively broad fiat bottom, said smoother and finisher being disposed so that it will lie above a previously formed curb or gutter when the wheels are disposed as aforesaid.

In testimony whereof, I hereunto affix my signature in presence of two witnesses.
